SPECIFICATION formingpart of Letters Patent No. 623,645, dated April 25, 1899.

Application filed June 10, 1898. Serial No. 688,071. (No model.) i

T0 at whom it may concern.-

Be it known that I, VILLIAM '1. YOUNG, a citizen of the United States, residing at Vineland, in the county of Cumberland, State of New J ersey, have invented a new and useful Improvement in Cultivator-Teeth, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of an improved construction of cultivator tooth, embodying means whereby the life thereof is prolonged and the operation of the tooth is rendered more effective than heretofore.

It further consists of novel details of construction, all as will be hereinafter more fully set forth, and particularly pointed out in the claims.

Figure 1 represents a side elevation of a cultivator-tooth embodying my invention. Fig. 2 represents a rear elevation of Fig. 1. Fig. 3 represents a section on line x 0;, Fig. 1.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, the tooth consists of a cutting-blade A, which is bent to form a curved or concaved surface B, the latter facing the line of direction of movement of the cultivatorwhen the tooth is secured in position. The blade Ais made of any suitable material and is carried by an iron or steel beam, brace, or post 0, which latter is provided with a curvature fitting snugly to the curved rear surface of the cutting-blade A.

D designates flanges which are located on each side of the cutting-blade, the same extending down the opposite edges thereof and partially inclosing' the brace or post 0, as will be understood from Figs. 1 and 3, and being of sufficient extent to receive openings or boltholes E, through which bolts or other fastening devices F pass, the latter passing also through the brace or post 0, as will be understood from Fig. 3, whereby it will be seen that the blade A is rigidly and securely held in position by means of the bolts F, and any lateral shifting isprevented by the flanges D, which engage the sides of the brace or post 0, as is evident.

In the specific embodiment of this invention illustrated in the drawings the blade is curved vertically, so that its point travels in advance of the body portion, and the sides of the'upper portion thereof are parallel, while the lower end portion tapers toward the point thereof. The said flanges follow the curvature of the sides of the body portion and taper toward their lower ends, merging at their lower ends into the said body portion.

It will be noted that the upper portion of the cutting-blade is extended above the post 0, while the lower portion or point thereof is projected below the lower portion of said post, and by reason of the series of openings E it will be seen that as the lower portion of the cutting-blade wears away by removing the boltFsaid blade can be adjusted downwardly and the life thereof greatly prolonged. brace or post 0 at its upper portion is deflected rearwardly, as indicated at G, and extends back sufficiently to form a lever provided with openings or bolt-holes H for attachment of said cutting-blade to any required angle of the line of directionof movement of the cultivator. I

It will be apparent from the foregoing that the point or cutting-face of the tooth, being an entirely smooth surface,will prevent clogging, whereby the efficiency of the tooth is destroyed, and it will also be evident that whenever the cutting-blade A becomes worn or damaged from any cause the same is easily accessible and can be readily adjusted, removed,or replaced,accordin g to requirements.

I desire also to call attention to myimproved.

manner. of attaching the cutting-blade to its supporting-post, it being noted that since I assemble the parts by means of the side flanges, having the fastening means passing therethrough, there is no clogging, and no weeds or other impediments can be caught upon the tooth, which occurs when the fastening-bolt passes through the cutting-blade and post in a line parallel with the direction of movement of the cultivator.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. The combination with the post of a cultivator, of a tooth removably secured thereto and consisting of a body portion, and lateral flanges extending rearwardly from the side edges thereof, and means passing through said flanges and post for fastening said parts.

2. The combination with the post of a cul- The.

livator, of a longitudinally-adjnstable tooth seen red thereto, said tooth com prising a body portion, and lateral flanges extending rearwardly from the side edges thereof, said body 5 portion and flanges fitting against faces of said post.

3. The combination with an upright post, of a longitudinally-adjnstable blade secured to the front side thereof, said blade compris- IO ing a body portion and lateral flanges extending rearwardly from the side edges thereof, said body portion and post being equal in width and said blade and post being of correlative eontour to provide a firm bearing, and securing devices passing transversely 15 through said flanges and post.
